SULKY-PLOUGH.

TO ALL WHOM IT MAY CONCERN: I

Be it hnown that I, JOHN H. RANKIN, of Versailles, Morgan ebuntgandState of Missouri, have invented a new and improved Sulky-Plough, ofwhich the followingis a fnll and clear description, reference being badto the accompanying drawings, making part of this specification. I I aMy improvement in ploughs relates to mechanical devices for elevatingone or more ploughs, so that the depth cut shall be .any desired one, orthat they may be removed entirely from the ground. Also, such anarrangement of adjusting-bars connected with the ploughs for regulatingthe angle between the plouglis and the round as shall be conducive toeconomy in ploughing. And, further, by pivoting the central ploughs foreand aft, facilitate the operation of billing, or. enable the operator toavoid obstacles.

Figure 1 represents a plan of my improved plough.

Figure 2 is a front elevation of the same, a part of the frontframing-timber being removed.

Figure'3 is a section elevation of my plough, the section being takenvertically in the plane indicated by the line 1-1 in fig. 1. v I

Ais the frame of the plough, to either side of which, at a suitabledistance back of the ploughs, is secured the gauging-plate B, from whichprojects the axle bearing the wheels B; the plate is perforated at a.Immediately beneath the frame A are the adjustable cultivators C andadjustable ploughs D. A cultivator, C, is placed outside of the'pair ofploughs D. The front ends of. both ploughs and cultivators 'are providedwith staples; which pass through eyes in the adjusting-bars b, securedto the front faceof the forward cross-rail of the frame A. The legs a ofthe cultivators G are hinged at c to the under sidesof the beams c. Ared or bar, 0', extends between and is pivoted to the leg 0 and beam 0of each cultivator. The rear ends-of the cultivators are retained ata'given distance apart by rail 01. Cords e, secured to the extreme rearends of the cultivators G, extendingrupwards, pass about drumsf,securely attached to the axle g, from which projects the handle It,conveniently located by the side of the operator. From the beams c,projecting upwards and through the cross-timber 7c of the frame A, arethe screws Z, having the regulatingm-uts 1 above the cross-timber k. Thelegs in of the ploughs D are pivoted to the inside faces of the beams m.Handles n extend from the plough beams m vertically to an altitudegreater than the seat E of the operator. The front ends of theplough-beams m are provided with staples, which pass through eyes in theadjustable bars .5, secured to the front face of the forward cross-railof the frame A. The rear ends of the plough-beams m are also providedwith staples, which pass through eyes 7b in the rod or bar cl. A strip,17, of metal or other desirable material, is pivoted to either handle n.A rod, 0, extends from the plough-beam m to the leg m in each of theploughs D.

Operation.

By means of the regulating-nuts l on the screws Z, the rear ends of thecultivators C and ploughs I) may, at the option of the operator, beelevated or depressed, according to the depth of ploughing desired, andby pressing forward the handle it the cords e are wound about thedrumsf, elevating the system of cultivators and ploughs entirely abovethe ground. In ploughing loose or light soil,'t-hc legs 0 and m of thecultivators C and ploughs D are set at an acute angle with the ground,by means of rods 0' and 0. Since the beams m of the ploughs D arepivoted fore and aft, the operator, may, by imparting a lateral motionto the handles 11., cause the ploughs to hill corn or furrow the groundnear one or the other of the cultivators, and also to readily avoidobstacles. The adjustment of both cultivators and ploughs is effected bymeans of the adjusting-bars b. By securing the gauging-plates B high orlow to the frame A, the cultivators and ploughs are removed from orcaused to penetrate the ground to a greater depth.

It will be seen that the various devices for adjusting the position ofthe cultivators and ploughs enable the operator to adapt one ploughtoe'very species of soil and kind of ploughing.

Having fully described my improved sulky-plough, the use and operationof its various parts, and set forth its advantages, I make the followingclaims, which I desire to secure by Letters Patent:

, 1. The cultivators C, constructed as above described and for thepurpose set forth.

2. The cultivators C, screw 1, nut l, cords .e, drumsf, on axle g, andhandle h,-in combination with the frame A, all' arranged as abovedescribed and for the purpose set forth.

3. The plcughs D, constructed as above described and for the purposespecified.

4. The cultiv'ators C, ploughs D, adjusting-bars b, rail d, screws -Z,nuts-Z, cords e, drums f,- on axle g, and handle 72, in combination withthe frame A, as above described and for the purpose set forth.
